Illustrates the features which are unique to birds of prey or raptors. Explains the characteristics of the four families of diurnal raptors (Falconiformes) and the two families of nocturnal raptors, or owls (Strigiformes). Because the raptors are intricately linked to the ecosystem, the ability of birds of prey to act as an early warning system for potential ecological disasters is stressed.
